Biopolymer derived superabsorbent for environmental sustainability: A review

Abstract

Increased environmental degradation and solid waste production has resulted in a higher demand for biodegradable materials based on biopolymers. Superabsorbent are three‐dimensional cross linked polymeric material that allow huge amounts of liquid to absorb. Synthetic superabsorbents (SABs) are extensively used as an absorbent of aqueous solutions for various applications, mainly as adult incontinence, feminine hygiene products etc. The major components of synthetic superabsorbents are acrylic/methacrylic acid. According to the report of US Environmental Protection Agency, the acrylamide used in the production of synthetic superabsorbent is extremely carcinogenic when exposed to people. On the other hand, A large number of synthetic Superabsorbent polymers are quite resistant to the environmental degradation process, and thus responsible for the accumulation of solid waste material. However, the presence of hazardous and undegraded content in the synthetic superabsorbents leads the designing of biopolymer based superabsorbents. These developed hybrid materials of superabsorbents are a combination of renewable raw materials and synthetic polymers. Biopolymer‐based superabsorbent has a lot of potential due to their excellent biocompatibility, biodegradability, and non‐lethal qualities. This review paper discusses the general perspective, characterization, and synthesis strategies for the production of hybrid superabsorbents. In addition, the methodologies for illustrating these superabsorbent hydrogels, as well as their prospective uses, are discussed.

An overview of biopolymer-derived packaging material

“…1 The enduring nature of conventional plastics, coupled with their non-biodegradability, has resulted in their persistent accumulation in landfills, posing an ongoing threat to ecosystems worldwide. [2][3][4] In India, the packaging industry consumes approximately 43% of the total annual synthetic polymer production, surpassing the global average of 39%. 5,6 This has contributed to the mounting waste problem, prompting initiatives to reduce single-use plastics; several countries restricted the use of plastic straws, cutlery, and stirrers since 2021.…”

Adsorption mechanism of E‐glass fiber/Aluminum particles/MWCNT filled epoxy matrix polymer composite in electronic applications

“…Glass‐reinforced epoxy composites are very strong materials used in roofing, automotive, and plumbing (Ku et al., 2011; Mittal et al., 2016; Sarikaya et al., 2019). Synthetic superabsorbent polymers are used in various applications as absorbents for aqueous solutions and have excellent resistance to environmental degradation (Sinha, 2022). E‐glass fiber is a well‐known form and a highly recommended material among researchers for mechanical qualities such as electrical, mechanical, chemical, and thermal capabilities, and so on.…”
